Does God cause evil?

“I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things. Isaiah 45:7, KJV
“Shall a trumpet be blown in the city, and the people not be afraid? shall there be evil in a city, and the LORD hath not done it?” Amos 3:6, KJV
“Out of the mouth of the most High proceedeth not evil and good?” Lamentations 3:38

The word translated evil should read calamity or disaster, and judgment in the Amos verse. There are more numerous scriptures clearly stating that God is not the author of evil. However, God has allowed evil at times to fulfill a higher purpose later.
